SPECIFICATION forming part of Letters Patent No. 388,125, dated August 21, 1888.

Application tiled Apiil 28, IP88. Serial No. T'JJSI. (No model.)

To aZZ whom it may concern.-

Be it known that l, LEROY W. FAIROHILD, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Corkscrews, of which the following is a specification.

This invention relates to corkscrews; and the invention consists in certain details ot'construction and certain combinations of parts or devices, as hereinafter more fully described.

Figure 1 is a side elevation of the corkscrew arranged for use, with a portion in section. Fig. 2 is aside view of the same when closed, with the handle and some of the parts in section. Figs. 3, 4, 5, and (5 represent portions detached to illustrate their construction.

This invention relates to that class of corkscrews designed to be carried about the person, the object being to produce a very compact, strong, and neat iinpleinent,one that will occupy but little space, and can be closed so as to exclude dust or dirt.

To construct my improved implement, I first provide a tube, A, of the proper length and size, as shown in Fig. 3, and cut therein three longitudinal slots, f, g, and h, as shown in said figure. The slot f extends about half the length of the tube A, while the sloth, which is directly opposite the slotf, is made to we tend from the center only part way toward the end, or of such a length as will permit the end a of the shank of the screw 13 to be turned up through it and project therefrom, as shown in Figs. 1 and 3. The other slot, 9, extends from the opposite end of the tube to near the center, as shown, to serve as a guide for the sliding yoke G, to which the shank of the screw B is pivoted.

The yoke Gis made of the proper size to permitit to slidefreely to and fro in the tube A,and has the shank of the screw B pivoted therein, as represented in Fig. 4, by a pin, a, so that the screw B can be turned in line with the longer axis of the yoke, as in Figs. 2and 4-, or at right angles thereto, as in Figs. 1 and 3.

To the end of the yoke O, I attach a spiral spring, t, the opposite end of said spring being secured to the end of the handle on its inside in any suitable manner, so that it will tend to draw the yoke 0 back toward the end of the handle, as in Fig. 2, and thereby draw in the screw B with it. I have shown the springias being connected to a small cup-shaped piece, p, of the same diameter as the tube A,against the end of which it will abut when the parts are assembled, as shown in Figs. 1, 2, and 3. It is obvious, however, that this disk or cup 1) may be dispensed with, and the spring be se-, cured direct to the end of the tube A.,or to the inside of the part I of the handle, it only be ing necessary to fasten it so as to hold it securely in place.

I provide a case composed of two tubes, I and I, of equal length, and both closed at their outer ends, as represented in Figs. 1 and 2. The part I is soldered or otherwise firmly secured upon that end of tube A which 0011- tains the spring, as shown in Fig. 2, and the part I is made to fit upon the opposite end of the tube A, it being provided on its interiorwith a spiral groove, 0, to engage with a pin or stud, e, which projects from the exterior of the tube A, as shown in Fig. 3, and by which it can be screwed on or off by a couple of turns. The groove 0 may be cut in the inner surface ofthe part I by making the latter thick enough for that purpose; but I prefer to cut it in a thinner tube, Z, as shown in Fig. 5, and then secure the latter within the part I, as it s a simpler and easier method of construction. The part I may be made of asingle tube of the proper thickness; or it may be made of thinner material ,and then have a thin tube corresponding to the tube Z in thickness inserted with n it before being secured upon the tube A, this being merely a matter of choice, as may be found most convenient in manufacture. By this construction and arrangement of parts it will be seen that when the screw B is turned up in line with the tube A the springt will operate to draw the yoke O, and with it the screw B back into the tube A to the posltion shown in Fig. 2, when the cap or part I can be screwed on, thus closing the whole up tight in a compact form, as represented in Fig. 2, in which form it can be conveniently carried in the pocket or valise, and will prevent the entrance of dust or dirt. WVhen it is desired to use the screw B, the cap I is detached, and the screw B is pulled out far enough to permit it to be turned to the position shown in Figs. 1 and 3, the spring acting to draw the shank of the screw snugly against the end of the part I, against which it will bear both above and below, as shown in Fig. 1. The cap I is then screwed 011, thus clamping the shank of the screw B firmly between the inner ends of the parts I and I, as shown in Fig. 1. The shank, as shown, is made rectangular in cross-section, and wider in the line of the slots than crosswise, so that it is held firmly therein and prevented from turning in the handle. When thus arranged, the tube A is re-enforced by the parts I and I, which altogether make a strong handle.

The parts I and I can be made of gold or silver, or may be plated and ornamented in any manner desired, thus combining utility and ornamentation.

Having thus described my invention,what I claim isi 1. The combination, in a corkscrew, of the tube A, provided with the slots h and f for the shank of the screw B, and the slot 9 at the side for the guide-pin'c, with the yoke 0, provided with the guide-pin c, and having the screw B pivoted thereto, as show u, whereby the shank of said screw is made to project through the slot h when turned into position for use, substantiall y as shown and described.

2. In combination with the tube A,provided with the slots f, g, and h, the yoke 0, provided with the guide pin c, and having the screw B pivoted thereto, and the spring t, connected at one end to the yoke O and at its opposite end to the end of tube A, or to the interior of the handle in any equivalent manner-,whereby the screw B will be drawn back within the case or handle, as set forth.

3. The combination of the slotted tube A, having the sliding yoke with the shank of the screw B pivoted thereto, so that its end 11 shall 40 project through the slot h and above the wall of tube A, with the cap I, secured rigidly on the tube A,'and the detachable cap 1, arranged to screw onto the opposite end of tube A, and

thereby clamp the shank of the screw B between it'and the adjoining end of tube I, substantially as shown and described.

4. Apocket-corkscrcw consisting of a tubular handle, a sliding yoke having the screws pivoted thereto, and a spring arranged to draw the yoke and screw back within the handle,

and a detachable cap for closing the handle,

all constructed and arranged to operate substantially as shown and described.

5. The combination, in a corkscrew, of the slotted tube A,with the sliding screw B therein, and having the cap I fastened on one end, with the detachable cap 1, arranged to screw onto the opposite end and abut against the end of tube I, so as to cover and completely LEROY W. FAIROHILD.
